Subject: Sort files by filename
This is really a general linux question. I have a series of files in a
format like this:
XXXX20070515_112011_942_10.bz2
XXXX20070515_112011_942_12.bz2 etc,
and I am trying to find a way to do 2 things, one, sort these files in
order, and then once in order, find the files that are numerically
missing based on the last 2 numbers in the file name. So if I have (as
above I want to know that file XXXX20070515_112011_942_11.bz2 is
missing. Can someone get me started on this, I'm stumped.
------------------------------
Try this to start out...
#!/bin/sh
last_seq_number=UNKNOWN
for f in `ls XXXX*bz2`; do
seq_number=`echo $f | cut -d'_' -f4 | cut -d'.' -f1`
if [ $last_seq_number != 'UNKNOWN' ]; then
diff=`expr $seq_number - $last_seq_number`
if [ $diff -ne 1 ]; then
echo "Missing Files"
fi
fi
last_seq_number=$seq_number
done
